The McGrath is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Reference): Primary Reference = Saunders, 1963
Comment (Workings): Workings / Exploration = A shaft driven to the 80-foot level soon after the vein was discovered caved in due to poor bracing. Since then, most of the prospecting has been confined to surface work and short shafts (Stein, 1957).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = This occurrence consists of a 7-inch-wide, low-grade, gold-quartz vein in schist (Chapman and Foster, 1969, p. D16; Saunders, 1963 [ATDM PE 58-13]). Stein (1957) reported that the vein strikes N80E and dips 60S. The upper portion of the vein is well oxidized; it grades into fresh sulfides at depth. The chief mineralization is jamesonite with associated gold and silver (Stein, 1957). A shaft driven to the 80-foot level soon after the vein was discovered caved due to poor bracing. Since then most of the prospecting has been confined to surface work and short shafts (Stein, 1957). There is no record of production.
Comment (Exploration): Status = Inactive
